抄録

Following the first report, the author tries to represent the oscillating velocity field of Navier-Stokes equation following Oseen's scheme in two-dimension by introducing a linear oscillating kernel function and the reciprocity theorem.<BR>The reciprocity theorem might serve as a tool for an approximate method to solve the boundary value problem and the eigen-value problem.<BR>For two examples on the hydrodynamic stability of laminar boundary layer and Karmanvortex street in the wake of a cylinder, the proposed method of approximation has made fit well the upper curve of the famous neutral stability of the laminar boundary layer and succeed to predict Strouhal number of a circular cylinder.
